Abstract
A light source device includes a substrate having a first surface, a plurality of light emitting elements disposed on the first surface side of the substrate, a bonding frame disposed on the first surface side of the substrate so as to surround the plurality of light emitting elements, and a cover disposed on an opposite side of the bonding frame to the substrate. The substrate has metal as a forming material. The cover includes a light transmissive member. The light transmissive member is opposed to the first surface of the substrate, and transmits the light emitted from the plurality of light emitting elements. The bonding frame is lower in thermal conductivity compared to the substrate.
